Quality Control

Our 1,3-Dichloro-1,3,5-Triazine-2,4,6(1H,3H,5H)-Trione Sodium Salt Dihydrate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, active chlorine content, and physical properties. Certificates of Analysis (COA) documenting these results are provided to guarantee traceability and compliance with your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. This material is hygroscopic (moisture-sensitive) and a strong oxidizer. Keep container tightly sealed to prevent moisture absorption and store separately from combustible materials, reducing agents, acids, and ammonia compounds. Recommended storage temperature: 15-25°C.
